fix: update API conformance test to point to new schema location (#3528)

# What does this PR do?

Update file paths in the conformance workflow to reflect the new location of the llama-stack-spec files from `docs/_static/` to `docs/static/`. Also update the `.gitignore` file to exclude Docusaurus-related directories (`docs/.docusaurus/` and `docs/node_modules/`).
